髓腔内植骨加记忆合金环抱器内固定治疗长管状骨骨不连

Application of Intramedullary Bone Grafting plus Internal Fixation of Memory Alloy Embracing Fixator to Treate Long Tubal Bone Nonunion

目的：探讨应用记忆合金环抱器治疗长管状骨骨不连.方法：应用记忆合金环抱接骨器加自体髂骨髓腔内植骨治疗四肢长管状骨骨不连21例.结果：21例患者经1~3年的随访均在3~6个月愈合,平均为4.5个月,所有病例均未发生感染.结论：本法操作简单,骨折端固定牢固,愈合快,并发症少,是治疗四肢长管状骨骨不连的一种新方法.

Objective： To investigate the application of memory alloy embracing fixator in the treatment of long tubal bone nonunion. Methods： 21 cases of limbs long tubular bone nonunion were treated with memory alloy embracing fix-ator plus intramedullary bone grafting of autogenous iliac bone. Results： In 1 to 3 years of follow-up, 21 patients all healed in 3 to 6 months, the average was 4.5 months, and had no infection. Conclusion： The method has the advantag- es of simplicity, fracture sites fixed solidly, fracture sites heal faster and fewer complications, so it is a new method to the treat limbs long tubular bone nonunion.
